This paper describes the novel on-machine measurement method of tool edge shape by using fluorescence emitted from cutting fluid. Tool wear and chipping are a major factor of decreasing machining accuracy. Therefore, on-machine measurement methods of tool edge shape with high accuracy are the subject of intensive study. Especially, considering the machining process, a robust measurement method with water-soluble cutting fluid is required for precise machining. For these reasons, the purpose of this research is to develop the technique that enables to measure tool edge shape precisely by using a confocal microscope. In order to achieve it, we have proposed the measurement method of tool edge shape by detecting fluorescence of cutting fluid adhering to the tool edge. Previous research has shown that it is possible to measure tool edge shape precisely by using oily cutting fluid. However, the applicability to water soluble cutting fluid is still remained. In particular, since water-soluble cutting fluid is used with dilution, it is worried that its fluorescence emission efficiency is lower than oily cutting fluid and the fluorescence detection is difficult. In this paper, it is shown that fluorescence could be detected from water-soluble cutting fluid. Then, the cutting tool edge shape adhering water-soluble cutting fluid is measured. These results show that the proposed method has high applicability to an on-machine measurement.
